Obviously never going to happen but here's who I think would get along with who, hate who, etc..
Let's start with Lee: Luke- I think he would respect him for caring for Clementine. Pete- He would see him almost as somewhat of a mentor and maybe even say he wants Pete to look after her. Nick- He would remind him of Ben but have sympathy for him. Rebbeca- Bitch up until episode 2 Alvin- Best friends Carlos- Mixed feelings Sarah- He would take her under his wing when Carlos is too ignorant to teach her survival skills. Carver- he would kill Carver immediately Sarita- He would think of her as Katjaa for obvious reasons.
Carley: Luke- Neutral relationship Pete- ? Nick- Ben 2.0 Rebbeca- Would bitch slap her in 5 minutes Alvin- they would be BFF's Carlos- Relationship? Sarah- Daughter-mother relationship
I'll do more later
